Missing link failure?

[99CivicSiBrian]

Whats up all?
So I have the Missing Link and thats great but I still get CEL 3 on my 95 coupe.
I have the Apexi NEO but not doing any correction currently. If I watch the NEO it shows a postive pressure from the MAP sensor, meaning the MAP is seeing boost. . . and hte Missing Link is letting it happen.
Anyone suffer a similar failure? Any ideas to try? Maybe someone local have one that I could temporarily swap to see if mine is bad or what?
Thanks

thts why you shouldnt use missing link.... what psi is this happening at?

It happens at about 1-3psi but at 4-8psi it is fine.

throw that s**t in the trash and get your ecu chipped and sell the neo

When I first boosted my civic I bought a missing link and it didn't work for s**t. I returned it , got another one but it still didn't work. So I got my money back and went to the pet store and bought a couple of one way check valves. Haven't had a problem since. I think I'm using like 2 or 3 check valves.

You're right thats what I'm working on today. . . trying to find a chip/chipper/plug and play/s300 or something. Word.

What exactly would that do for the car?

 

[majorahole]

bleed off the boost so your ecu doesn't see it

exactly like "majorahole" said





It acts like a missing link is supposed to I know alot of people that use this setup, I'm not that clever to think that up. It works tho and only cost like a dollar or two.

sooo do you just put them on a random vacuum line? Or what?

on the vacume line that goes to your map sensor, that's where I have mine.

But you have a firewall mounted map, right?

 

[bizoneoeh]

Actually, I have both but using the firewall mounted one. It works on either one tho.

 

[Phantom Civic]

how would you use a check valve on the other style?

on the f**kin vacume line dude

get a gm 3 bar map....if you look up a map sensor at your local autoparts store for a 1990 gm turbo Diesel truck youll be goood

so they will work inplace of the OEM one and not throw a CEL right?
just need to check.

ya, but you need to get a gm connector too, and i only think it will work correctly if you chip your ecu and choose the gm3 bar under the boost tools.
